Portable modular crisis communication system

A portable modular crisis communication system has a portable network operating center (NOC) unit and a deployable communications unit. The NOC and the deployable communications unit are communicably coupled through a network established by one or more portable networking antennas, and each have communication devices so that a NOC operator can communicate over the network with a subject through the deployable communications unit. The deployable communications unit may enable various features, such as covert surveillance, voice stress analysis, chemical threat detection, fingerprint reading, heartbeat monitoring, and radio disruption, among others.
